本発明は、金属基体と結晶化ホーロ一層との密着強度を
改善した結晶化ホーロー基板に関する。DETAILED DESCRIPTION OF THE INVENTION C. Technical Field of the Invention The present invention relates to a crystallized hollow substrate with improved adhesion strength between a metal base and a single crystallized hollow layer.
金属基体の表面に結晶化ホーロ一層′ｆ：形成した結晶
化ホーロー基板は、ガラスホーロー基板と比べて以下に
示す種々の利点を有していた。The crystallized enamel substrate formed with a single layer of crystallized enamel 'f: on the surface of the metal substrate had the following various advantages compared to the glass enamel substrate.
（７） ガラスホーロー基板では、ペースト焼成温度６

ボーロ一層の参化点が上昇する。(7) For glass enamel substrates, paste firing temperature 6
By repeatedly firing at 00-650℃,
In some cases, the hollow layer on the surface of the metal base becomes soft,
In the case of the crystallized glass hollow substrate O, the crystallization point of the crystallized boron increases due to crystallization.
（イ） 結晶化ホーロ一層が結晶質であるため、結晶化
ホーａ一層上に印刷焼付した抵抗体をし〜デでトリミン
グしても、クラックの発生が少なく、抵抗体の信頼性が
高い。(a) Since the crystallized hollow layer is crystalline, even if a resistor printed and baked on the crystallized hollow layer is trimmed with -D, there are few cracks and the reliability of the resistor is high.

い。ri) Since the single layer of crystallized enamel has high viscosity during firing, it is less likely to cause localized build-up on the edges of the metal substrate due to surface tension during firing, and the conductor at the edge, Good printing properties for printing pastes such as cleaning agents.
に）結晶化ホーロ一層はアルカリ金属酸化物を少量しか
含まないた袷、該ボーロ一層上に形成されゐ導体、抵抗
体勢への影替が少なく信頼性が高い。(b) The single layer of crystallized hollow metal is formed on the single layer of the metal oxide containing only a small amount of alkali metal oxide, and is highly reliable because it has little effect on the conductor or resistance state.
しかしながら、結晶化ホーロー基板は、ガラスホーロー

化ボーロー基板を繰り返し焼成した場合、該ポーロ一層
が下地金属から剥離するという欠点があった。However, although the crystallized enamel substrate has the various advantages mentioned above compared to the glass enamel substrate, the adhesion strength of the crystallized enamel to the metal substrate VC is low, and it forms a conductive film yeast of a resistor in a conductor. Therefore, when the crystallized Borrow substrate is repeatedly fired, there is a drawback that the single layer of Borrow peels off from the underlying metal.

界層の発達が十分でないためと推測される。このような
ことから、金属基体表面を粗面化することにより密着強
度を大きくしようとする方法が試みられているが、現在
までのところ好ましい結果が得られていない。The cause of this peeling is not clear, but it is presumed that it is because the boundary layer made of glass, which serves to connect the * group substrate and the crystallized hollow layer, is not sufficiently developed. For this reason, attempts have been made to increase the adhesion strength by roughening the surface of the metal substrate, but so far no favorable results have been obtained.
